摘要:
过渡\|稀土混合金属单分子磁体簇合物近几年已引起越来越多国内外科研人员的重视，原因在于磁各向异性较大的稀土离子引入到过渡金属簇合物中可提高单分子磁体的能垒及其阻塞温度.锰、铁、钴、镍、锌等金属盐与磁各向异性较大的稀土离子在适当配体存在下反应可制得相应的混合金属簇合物.通过文献调研发现，锰\|稀土簇合物中至少有一个磁各向异性较大的三价锰离子，合成出的主要有环状八核、线形三核、铃形十三核等化合物；铁\|稀土簇合物仅有少数被合成出来，可能由于其结晶比较困难且有微量的顺磁性铁离子夹杂在晶体中；钴\|稀土簇合物中钴和稀土离子都有较大的磁各向异性，两种离子混合可进一步提高磁各向异性；此外，镍或锌与稀土形成的簇合物也有一些文献报道.该综述可为人们设计更高能垒的单分子磁体簇合物提供更加广阔的研究思路.
Abstract:
Transition\|rare earth mixed metal single molecule magnets clusters have been received a wide attention from numerous scientists at home and abroad,mainly because introducing rare earth metal with large magnetic anisotropy to the transition metal clusters can improve their energy barrier and blocking temperature. Manganese,iron,cobalt,nickel,zinc ions reacting with rare earth ions in the solution containing suitable ligands can obtain corresponding transition rare\|earth mixed metal clusters. According to the literature reported by other people,manganese\|rare earth clusters contain at least one trivalence manganese ion,and cyclic octanuclear,linear trinulear,double\|cubane hexanuclear clusters have been reported; iron\|rare earth clusters have only very few examples mainly because their crystal can not easily grow and few paramagnetic iron ions are mixed with crystal; in the cobalt\|rare earth clusters,both cobalt and rare earth possess large magnetic anisotropy,and mixing two kinds of ions can further improve the anisotropy of the clusters. Moreover,nickel\| or zinc\|rare earth clusters have been also reported. The research status quo of the mixed metal single molecule magnets was provided to offer a more rational research project to improve the blocking temperature of single molecule magnets for other research groups.
